It doesn't have a proximity senzor! it works with KIES, also: NO picture editor, no document editor
At least Romanian version does not have those. is very well optimised, very clear sound (both multimedia and voice call); pretty good life battery (3 days with a 2G and a 3G SIM card in it - both active!).
In rest an all around great phone! had it for a week and I love It!

This phone has no proximity detector.Every time while calling screen is locked and you need to unlock everytime.There is also problem to start data service quickly.Also one more major problem is that when screen goes off it takes long time to start after pressing button.So many lakunas as compare s5570.not worth of money.

Samsung are telling us to believe that the galaxy s cannot run on ICS and now they've released this S duos with the same specs as the galaxy s. They take we consumers as fools thinking we will buy for them to get the profit they need. We are very sorry not to buy this phone UNCLE SAMMY.
